| Abstract: | An extension neural network prediction model based on particle swarm optimization(PSO)is proposed,the number of newly diagnosed coronary pneumonia in foreign countries was fitted and predicted by extension neural network model,and the weight was optimized by particle swarm optimization(PSO),compared with LSSVM,ABC-LSSVM and PSO-LSSVM models.The results show that the particle swarm extension neural network model proposed in this paper has a better fitting effect,higher precision and better performance than the other three models.It is suitable for the epidemic research of COVID-19. |
